Edgar Cayce Reading 97-2

In the application of self as towards will's influence: This the
factor through which one develops or retards in the earthly
experience.

The Gospel of Strength - Swami Vivekananda

Know that every thought and word that weakens you in the world is the
only evil that exists. Whatever makes man weak and fear is the only
evil that should be shunned.

The greatest sin is to think yourself weak.

I beg you to understand this one fact - no good comes out of the man
who day and night thinks he is nobody. If a man day and night thinks
he is miserable low and nothing, nothing he becomes... That is the
great fact which you ought to remember.

The Gospel of Strength - Swami Vivekananda

Whatever you think, that you will be. If you think yourselves weak,
weak you will be; if you think yourselves strong, strong you will be;
if you think yourselves impure, impure you will be; if you think
yourselves pure, pure you will be. This teaches us not to think
ourselves as weak, but as strong, omnipotent, omniscient.

The Gospel of Strength - Swami Vivekananda

First you have to build the body by good nutritious food -- then only
will the mind be strong. The mind is but the subtle part of the body.
The only test of good things is that they make us strong. As soon as
you say,"I am a little mortal being," you are saying something which
is not true, you are giving the lie to yourselves, you are hypnotising
yourselves into something vile and weak and wretched.

The Gospel of Strength - Swami Vivekananda.

Strength is the medicine for the world's disease. Strength is the
medicine which the poor must have when tyrannised over by the rich.
Strength is the medicine that the ignorant must have when oppressed by
the learned.

Non-injury is right; "resist not evil" is a great thing--these are
indeed grand principles; but the scriptures say, "... if anyone smites
you on your cheek, and you do not return him an eye for eye, a tooth
for a tooth, you will verily be a sinner."

This is very true, and this is a thing which should not be forgotten.
Heroes alone enjoy the world. Show your heroism... Otherwise, you live
a disgraceful life if you pocket your insults when you are kicked and
trodden down by anyone who takes it into his head to do so; your life
is a veritable hell here, and so is the life hereafter. This is my
advice to you... Of course do not do any wrong, do not injure or
tyrannise over anyone, but try to do good to others as much as you
can. But passively to submit to wrong done by others is a sin... Try
to pay them back in their own coin then and there. If you cannot do
that, how do you profess to be a man?

Edgar Cayce Reading 3245-1

Know that ye are going through a period of testing. Remain true to all
that has been committed to thee, and know that each day is an
opportunity, and an experience. Speak a word for thy ideal. Not as to
force an issue but ever constructive. Sow the seed of truth, the seed
of the spirit. God will give the increase.

Edgar Cayce Reading 451-2

. . that contentment that can only come with the knowledge of His
peace abiding ever with thee; for with His peace there comes
contentment, no matter what may be the vicissitudes of life, whether
in trials as of the mental surroundings, whether in the trials as of
material conditions or positions, there can come--with that
peace--that contentment of heart and mind, that He is in His holy
temple and all is well with those who have made Him the ideal . . .

Edgar Cayce Reading 1603-1

In the manner, the way ye attend, ye treat or ye hold--in thy mental
self--thy brother's position, or thy neighbor's or thy friend's as thy
own, that is the manner, the concept ye hold of thy Creator!

Edgar Cayce Reading 1469-1

For the entity, as each soul, is a portion of the whole. Thus, though
a soul may be as but a speck upon the earth's environs, and the earth
in turn much less than a mote in the universe, if the spirit of man is
so attuned to the Infinite, the music of harmony becomes as the divine
love that makes for the awareness in the experience of the Creative
Forces working with self for the knowledge of the associations with
same.
